Signals from motion

This project investigates whether human body motion is a biological signal system. We are examining the kinds of fitness-relevant information conveyed by everyday body motion, how this information is perceived by observers, and to what extent this information is reliable or deceptive. A detailed description of this programme is available here.

Sample Stimuli

Perceived health from motion

These are sample motion stimuli, for recent work showing that perceived health from biological motion predicts vote choice. This is the case even for short motion clips such as those below, showing only a simple turning movement. Raters can differ in which clip they judge to be healthier, but the best predictor of their vote choice is not attractiveness or perceived leadership, but perceived health.

Links are to QuickTime movies. Robin Kramer made these stimuli using his custom software. Clips are taken from video of the second Obama-McCain presidential debate, and from speeches by Brown and Cameron to the House of Commons.

3D motion tracking

The video below is an example from Bangor’s new motion tracking system. This system records the motion of tracking points in 3D space.
